While the giant, icy worlds are similar in many ways, a thinner, more active haze makes Neptune more blue than Uranus.
Some of the most famous images of Venus make the second planet from the Sun appear blue. However, we know that Venus actually appears mainly yellow-white to the naked eye. This blue tinting observed in some photos is as a result of the filters the cameras have used to take the image.
Neptune, the other blue planet, is the eighth planet in our solar system. Neptune is an ice giant.
The predominant blue color of the planet is a result of the absorption of red and infrared light by Neptune's methane atmosphere. Clouds elevated above most of the methane absorption appear white, while the very highest clouds tend to be yellow-red as seen in the bright feature at the top of the right-hand image.
This color is not due to the presence of oceans, but is caused by the effects of a 2,000-degree-Fahrenheit atmosphere where silicate particles melt to make "raindrops" of glass that scatter blue light more than red light. The planet HD 189733b was discovered in 2005 and is only 2.9 million miles from its parent star.
A purple planet! Actually, the color suggestion is just speculation based on the planet's expected chemical composition. The planet, called WASP-104b, orbits 4 million km from its yellow dwarf parent star every 1.75 days.
Saturn is also a giant gas planet with an outer atmosphere that is mostly hydrogen and helium. Its atmosphere has traces of ammonia, phosphine, water vapor, and hydrocarbons giving it a yellowish-brown color.
Viewed through a telescope, Venus presents a brilliant yellow-white, essentially featureless face to the observer. Its obscured appearance results from the surface of the planet being hidden from sight by a continuous and permanent cover of clouds.
Alt text: Pluto is shown in a rainbow of colors that distinguish the different regions on the planet. The left side of the planet is mostly blue-green with purple swirls, while the right side ranges from a vibrant yellow-green at the top to a reddish orange toward the bottom.
The planet looks blue from outer space since two-thirds of the surface is covered with water, so it is called a blue planet. That is 71% of the earth is covered by water.
Venus has an optical phenomenon called a 'glory' which – like a rainbow – forms when sunlight falls on cloud droplets. However, glories are caused by the interference of light waves within droplets, whereas rainbows are caused by the reflection, refraction and dispersion of light.
Uranus gets its blue-green color from methane gas in the atmosphere. Sunlight passes through the atmosphere and is reflected back out by Uranus' cloud tops. Methane gas absorbs the red portion of the light, resulting in a blue-green color.
The blue-green color results from the absorption of red light by methane gas in Uranus' deep, cold and remarkably clear atmosphere.
For the average stargazer, Mercury might look like a dull, grey blob in space. But up close, it's a different story. Thanks to images from NASA's Messenger probe, the solar system's innermost planet looks iridescent blue with patches of sandy-colored plains with strands of grayish white.
Pluto is thought to have a rocky interior and perhaps a subsurface ocean, while its surface is covered with ice composed of water, methane and nitrogen. According to the space agency, Pluto's surface is cratered, white, tan and brownish-red in colour.
A: The outer atmosphere of Jupiter is mostly hydrogen and helium, with some water droplets, ice crystals, and ammonia crystals. When these elements form clouds, they create shades of white, orange, brown, and red, the colors of Jupiter.
Mercury has a dark gray, rocky surface which is covered with a thick layer of dust. The surface is thought to be made up of igneous silicate rocks and dust.
But what makes them take on all their various hues, and why does each one look so different? The planets of the solar system are varied in their appearance. Mercury is slate gray while Venus is pearly white, Earth a vibrant blue, and Mars a dusky red.
Named GJ 504b, the planet is made of pink gas. It's similar to Jupiter, a giant gas planet in our own solar system. But GJ 504b is four times more massive. At 460°F, it's the temperature of a hot oven, and it's the planet's intense heat that causes it to glow.
The Greeks named the fourth planet 'Mars' as the 'bloody planet' or a 'red planet' because this planet shines in sky with red colour resembling blood. Mars is a hot, dry, fiery and violent planet.
Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth.
Planet Earth III will be the third part in the Planet Earth trilogy. It is set to release in 2023.
Venus has a thick, toxic atmosphere filled with carbon dioxide and it's perpetually shrouded in thick, yellowish clouds of sulfuric acid that trap heat, causing a runaway greenhouse effect. It's the hottest planet in our solar system, even though Mercury is closer to the Sun.
